Workouts when your back or knees hurt: what you can and can’t do
When you need a doctor, what to do for lower back and knee pain, a table of substitutions for different limitations, how to tell “unfamiliar” from “not allowed,” and where to start.
Movement is not just about workouts. Walking, which no one considers a sport, provides half the benefit; rest and sleep do what the workout was meant to do; and backs and knees that “get in the way of exercising” most often ask not for rest, but for the right movements. This section is about movement off the mat: steps, recovery, and training with limitations. The main article on the topic is training and movement according to the method.
7-10 thousand
steps per day
benefit levels off thereafter
24-72 h
muscle soreness after exercise
normal during the first workouts
7-9 h
of sleep for recovery
muscles grow at night

sharp joint pain
must not be endured — change the movement
Seven to ten thousand steps a day are the most underrated tool of the method. Large reviews from recent years show that health benefits increase up to about 7-8 thousand steps in people over sixty and up to 8-10 thousand in younger people, then level off. Walking smooths out blood sugar after meals, improves sleep, and maintains energy expenditure on days without strength training — and requires neither special gear nor time «for exercise».
How to get your steps in without scheduled walks, why 10 minutes after a meal matters more than an hour in the morning, and what to do in winter — walking 7-10 thousand steps.
Training is the signal; growth happens during rest. Muscle protein synthesis is elevated for 24-48 hours after exercise, and this is exactly when protein and sleep are needed—not another workout for the same muscle group. Muscle soreness a day or two later is normal the first few times, subsides by the third day, and almost disappears by the third workout; light walking relieves it faster than rest.
How much rest to take, how to distinguish beneficial soreness from harmful pain, and why lack of sleep takes away more than an extra workout gives you — recovery: sleep, rest and muscle soreness. For sleep in general — sleep on LCHF.
| Symptom | Normal | Warning sign |
|---|---|---|
| Muscle soreness the next day | first 2-3 workouts, 2-3 days | longer than five days, swelling, dark urine — see a doctor |
| Fatigue after a workout | mild, passes within an hour | less energy all day — it was too much |
| Knee or lower back pain | aching after an unfamiliar movement, goes away within a day | sharp, during movement, keeps recurring — change the movement; if severe — see a doctor |
| Dizziness during a workout | — | almost always salt and water; if it does not go away — see a doctor |
| Feeling sleepy afterward | normal if you sleep 7-8 hours at night | if you are not getting enough sleep — sleep first, then work out |
Drink more water, add salt, and rest.
A painful back and knees are not a ban on movement, but a reason to choose the right movements. Rest almost always makes things worse: the muscles that support the joint weaken, and the load on the joint itself increases. For the back, the core and glutes work well — planks, bridges, and bird dogs — while weighted bends and twists do not. For the knees — squats to a chair rather than deep squats, steps instead of jumps, and hip strengthening.
What you can and cannot do in each case, how to distinguish “unfamiliar” from “not allowed,” and when you need to see a doctor before starting — training when your back or knees hurt. In the program, limitations are taken into account when selecting exercises: movements with contraindications are not included.
Every hour—two minutes of standing or walking. This isn't a workout but prevention: your back hurts after a day because of eight hours without movement, not because of the load. In the evening—10-15 minutes of mobility.
You already get the steps—you’re missing strength training. Twice a week, 20 minutes at home: core, glutes, back. Let your legs rest lying down with your lower legs elevated.
Strength training is mandatory, walk every day, recovery takes longer—48-72 hours for one muscle group. More details—“the after-40 method”.
Sleep first, then train. When sleep-deprived, your body does not recover from the load, and stress increases. Train no later than 3 hours before bedtime.
10 minutes of walking after a meal lower the glucose spike more noticeably than an hour in the morning.
Regular movement during the day is one of the most reliable ways to fall asleep faster.
8-10 thousand steps amount to hundreds of kilocalories a day that you barely notice.
Walking and mobility help prevent pain that rest only makes worse.
7-8 thousand per day is the point after which the benefits grow slowly. 10 thousand is a good benchmark, but not a mandatory minimum.
A different muscle group—yes. The same one—not until the soreness becomes mild. Walking and mobility—any day.
Modify the movement: squat to a chair, reduce the depth, widen your stance. If sharp pain remains—see a doctor, don’t push through it.
A week—nothing is lost. Two weeks—strength is almost unchanged, endurance drops slightly. A month—return one level lower.

Where muscles actually grow, how to distinguish beneficial soreness from harmful pain, how much to rest, why lack of sleep takes away more than an extra workout gives, and what overtraining looks like in a beginner.
How many steps are actually needed, why ten minutes after a meal matter more than an hour in the morning, where to get steps during an ordinary day, and what to do in winter.
